INSPECTION PROCEDURE1. DISCONNECT DISTRIBUTOR CONNECTORS.
2. REMOVE DISTRIBUTOR CAP.
3. REMOVE ROTOR.
4. REMOVE IGNITION COIL DUST COVER.
NOTE: Cold and Hot in the following sentences express the temperature of the coils themselves.
Cold is from -10°C (14°F) to 50°C (122°F)
Hot is from 50°C (122°F) to 100°C (212°F)
5. INSPECT PRIMARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
Primary Coil resistance
- Cold: 0.36 - 0.55 Ohms
- Hot: 0.45 - 0.65 Ohms
- If the resistance is not as specified. replace the ignition coil.
6. INSPECT SECONDARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary Coil resistance
- Cold: 9.0 - 15.4 k ohms
- Hot: 11.4 - 18.1 k ohms
- If the resistance is not as specified, replace the ignition coil.
7. INSTALL IGNITION COIL DUST COVER.
8. INSTALL ROTOR.
9. INSTALL DISTRIBUTOR CAP AND HIGH-TENSION CORDS.
10. RECONNECT DISTRIBUTOR CONNECTORS.
